B1D17-11-PASSENGER MIRROR HORIZONTAL POSITION SENSOR INPUT - CIRCUIT SHORT TO GROUND





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The memory system is able to store and recall all exterior outside mirror positions. The system can be set for two different drivers. The memory mirrors have a variable resistor (potentiometer) that measures the resistance of the vertical and the horizontal position of the mirror. This value changes anytime the mirror is moved.

- When Monitored:
Continuously.

- Set Condition:
The Door Module senses a short low on the (P68) Passenger Mirror Horizontal Position Signal circuit for more than two seconds.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the can tool, record and erase DTCs.
3. Turn the turn signal on, if equipped with turn signal mirror.
4. Turn the puddle lamps on, if equipped with puddle lamp mirror.
5. Turn the rear defogger on, if equipped with heated mirror.
6. Press and release the Mirror Select switch to select the Passenger Outside Rearview Mirror.
7. Operate the Mirror Adjust switch in all directions several times while monitoring the scan tool for DTCs. NOTE: After adjusting the mirror in one direction wait at least two seconds before adjusting the mirror in the opposite direction, as this will allow time for an active fault to set if present.

Does the scan tool display B1D17-11-PASSENGER MIRROR HORIZONTAL POSITION SENSOR INPUT - CIRCUIT SHORT TO GROUND?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. For vehicle's equipped with folding outside rearview mirrors, repeat test with mirror folded. If DTC is now active, Go To 2.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Passenger Outside Rearview Mirror C1 (Component Side) harness connector from the Door Module.
3. Measure the resistance between ground and the (P68) Passenger Mirror Horizontal Position Signal circuit.

Is the resistance below 10K Ohms?

Yes

- Repair the short to ground in the (P68) Passenger Mirror Horizontal Position Signal circuit. If the wiring harness and harness connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. CHECK (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO (P66) PASSENGER MIRROR SENSOR GROUND CIRCUIT




1. Measure the residence between the (P68) Passenger Mirror Horizontal Position Signal circuit and the (P66) Passenger Mirror Sensor Ground circuit.

Is the resistance below 1.0K Ohms?

Yes

- Repair the (P68) Passenger Mirror Horizontal Position Signal circuit for a short to the (P66) Passenger Mirror Sensor Ground circuit. If the wiring harness and harness connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. CHECK (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO ANY OTHER MIRROR SENSOR GROUND OR RETURN CIRCUITS




1. Disconnect the Passenger Outside Rearview Mirror C2 (Component Side) harness connector from the Door Module.
2. Measure the residence between the (P68) Passenger Mirror Horizontal Position Signal circuit and all other mirror sensor ground and return circuits.

Is the resistance below 10K Ohms between the (P68) Passenger Mirror Horizontal Positional Signal circuit and any other Ground or Return circuit?

Yes

- Repair the (P68) Passenger Mirror Horizontal Position Signal circuit for a short to a Sensor Ground or Return circuit. If the wiring harness and harness connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. CHECK (P68) PASSENGER MIRROR HORIZONTAL POSITION SIGNAL CIRCUIT FOR A SHORT TO ANY PASSENGER MIRROR DRIVER CIRCUIT.




1. Measure the resistance between the (P68) Passenger Mirror Horizontal Position Signal circuit (C1-9) and Passenger Mirror Driver circuits in the Passenger Outside Rearview Mirror C1 and C2 (Component Side) harness connectors.

Is the resistance below 10K Ohms for any measurement?

Yes

- Repair all circuits with a resistance below 10K Ohms for a short to the (P68) Passenger Mirror Horizontal Position Signal circuit. If the wiring harness and harness connector are okay, replace the Passenger Outside Rearview Mirror. Outside Rearview Mirror - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Inspect the wiring and harness connectors for damage and repair as necessary. If the wiring and harness connectors are okay, replace the Door Module. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
